T0 LZZ whom t Muay concern/: Y

Be it known that I, WILSON W. CAREY, a citizen of the United States, anda resident of Lowell, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Buzz or I-Iand Planing-Machines, of which the following is a specification.

This invention relates to improvements in buzz or hand planing-machines; audit consists in mechanism for vertically adjusting the rotary knife-cylinder relative tothe upper surface of the back table in such amanner as to cause the cutting edges ofthe rotary knives when in their highest position to be in horizontal alinement-withthe upper surface of the back table,l as will hereinafter bemore fully shown and described, reference being had to the accompanying drawings,wherein-A Figure lis a partial side elevation of a buzz or hand planer provided with my improved knife-cylinder-adjusting device. Fig. 2 is a top plan view of Fig. 1. Fig. 3 isa cross-section on the-line 3 3 shown in Fig. l; and Fig. 4 is a side elevation similar to Fig. l, showing a modificationV of the invention.

Similar letters referto similar parts Wherever they occur on the different parts of the drawings.

A represents the standard of a buzz or hand planer.

B represents the vertically-adj ustable front table, and C represents the back table longitudinally adjustable upon the frame D, that is secured to the said standard, as is usual in machines of this kind.

E is the rotary knife-cylinder, the cylindrical ends e e of which are j ournaled in bearings attached to the vertically adjustable head-stock F, as usual in machines of this kind.

G G are the cutter-knives, secured to the rotary knife-cylinder, as usual.

The frame D terminatesat its forward end head-stock F corresponding ears F F', as shown in Figs. l, 2, and 3.

I is a preferably polygonal head of a screwbolt, the ends i 'i' of which are screw-threaded inopposite directions-that is, one is made with a right-hand thread and theother with a left-hand thread, as shown in Figs. 1 and 3. The said screw-threaded ends of the bolt are screwed into corresponding screw-threaded perforations in the ears D" and F', respectively. There is one of such adjusting devices inA either end of the head-stock, as shown in Figs. 2 and 3. If it is desired to adjust the knife-cylinder to its proper height relative to the top of the back table C, it is only necessary to turnthe adjusting-screws I I to the right or left, as required, thereby causing the head-stock and its attachments to be raised or lowered for the proper adjustment of the cutting-knives relative to the top of the back table C. After being so adjusted the headstock maybe securely clamped in its adjusted position by tightening the screws H H.

Although in practice I prefer to` employ adjusting-bolts screw-threaded in both ends,one with a right and one with a left thread, I may, if so desired, use a modification, as shown in Fig. 4, in "which the head-stockear Ff only is internally screw-threaded and adapted to receive a screw I', that is journaled in the stationary ear O11 the frame D, but-prevented from moving longitudinally therein, it being for such purpose provided with a collar i below? the stationary ear D3 and with a polygonal'head 3 above said ear, as shown in Fig. 4, by which arrangement the head-stock and its attachments may readily be adjusted for the purpose hereinabove set forth. By this arrangement I am enabled to adjust the position of the knife-cylinder during the running Y of the machinewithout the need of stopping it, thus saving valuable time in the adjustment of the parts mentioned.

`It will be seen that the cutter-carrying headstock is of substantially yoke-shape form, the transverse portion thereof bearing atwise against the framework of the machine and the arms of said head-stock constituting effective supports in which thejournals of the cutter can rotate, and by reason of said fiat bearing the head-stock when the holding- IOC firmly against chattering. The said headstock has lugs at its opposite ends in vertical alinement with cooperating lugs on the framework, and these lugs are connected by the justing means and solidly held in its adjusted position, the whole forming a simple and effective organization of parts.

Having thus fully described the nature, construction, and operation of my invention, I wish to secure by Letters Patent and claim- .1. In a buzz or hand planing-machine, the combination of back and front tables, a cutter-carrying head-stock of yoke form, the transverse portion of which is adapted to bear flatwise against the framework of the machine, and such framework having elongated vertical slots, screws adapted to pass through the respective slots, and the transverse portion ofthe head-stock having tapped seats to receive said screws, and said headstock having lugs at its opposite ends, and

ranged in vertical alinement with the other lugs, and independent adjusting means connected with the respective lugs.

2. In a buzz or hand planing-machine, the combination of back and front tables, a cutter-carrying head-stock of yoke form, the transverse portion of which is adapted to bear iiatwise against the framework of the machine, and such framework having elongated vertical slots, screws adapted to pass through the respective slots, and the transverse portion of the head-stock having tapped seats to receive said screws, and said head-stock having lugs arranged in vertical alinement with the other lugs, and rightand left handed adjusting-screws tapped into the respective lugs.

In testimony whereof I have aixed mysignature in presence of two witnesses.
